Baxter preached in Nashville at the Trinity Lane Church of Christ from 1946 to 1951,[4]:171 and preached at the Hillsboro Church of Christ in Nashville for 29 years from 1951 to 1980 when he retired.[1] During much of this time, his sermons were recorded for broadcast on WLAC radio on Sunday nights. He was considered by many to be "the best preacher of the Churches of Christ during his lifetime."[3]:607 He advocated a method of preaching that focused on meeting the particular needs of his listeners and tailored the content and techniques used to the "life-situation" of the particular audience.[3]:607 Baxter's style was very different from the harder style that originated in the debating tradition of the Churches of Christ, emphasizing a "softer" gospel of love.[3]:607 He trained hundreds of younger preachers and his influence was such "that at one time many could readily tell if a preacher had trained at Lipscomb college."[3]:607

Baxter was also a writer for the Gospel Advocate and 20th Century Christian.[4]:171 He wrote eleven books including Speaking for the Master, I Believe Because, and When Life Tumbles In.[2] He coauthored two books, and coedited seven more.[2]:71 He became the regular speaker for the Herald of Truth television program in August 1959.[1] When the program went to a radio series, he was featured periodically.[2]:71

In his youth, Baxter was an avid tennis player, winning the city championship in the boys' (14 and under) classification in Nashville, Tennessee.[citation needed]
